i don't really know anything about cars, but ever since recieving my audi a6 2.7t im eager to learn, i was wondering what parts i would need to get my audi to sound deeper/louder/better, is it just the tailpipes or a whole new exhaust system, if i did buy one who would i get to install it, also what about these chips, what exactly do they do and what specific kind would be best for my car,
